Global Navigation Satellite Systems Engineering, Policy, and Design
I read with great enthusiasm Dee Ann Divis’ article New Chimera Signal Enhancement Could Spoof-Proof GPS Receivers. Logan Scott is one of the brightest people I know, and I very much enjoyed his presentation about Chimera last week at the National PNT Advisory Board’s public meeting in Alexandria, Virginia.

Location privacy is on the minds of lawmakers from both parties with provisions about disclosure, data collection and sharing in more than half a dozen bills. There is also language in a House appropriations bill nixing the use of federal funds for GPS tracking.

An increasing number of applications require accurate, reliable, and traceable signals for time and synchronization. Key fields of application include banking and finance, telecom networks and electricity grids. GMV’s WANTime is a new time service for the city of Madrid, Spain, distributed using the White-Rabbit network protocol over optical fiber. A pilot customer of the service is currently the Madrid Stock Exchange (Bolsa de Madrid), connected to GMV’s datacenter by a network link of around 50 kilometers.

In the past few months, there have been articles in the press providing information and misinformation in advance of the GPS week rollover that occurred on April 6. Readers were warned to retire obsolete receivers, update software, check with manufacturers, and even perform testing of critical devices.

Nominations are now being accepted for the Institute of Navigation Satellite Division’s prestigious Johannes Kepler Award – the annual award honoring an individual during their lifetime for sustained and significant contributions to the development of satellite navigation and the Bradford W. Parkinson Award – the award recognizing an outstanding graduate student in the field of Global Navigation Satellite Systems (GNSS).

Hostile cyber operations such as jamming and spoofing of GNSS signals are a growing concern. While they do not cause major damages to the satellite navigation system as such, they can have severe effects on critical national infrastructures and many other systems. Here, we address how international telecommunications law as well as the international law on the prevention of war apply in this context.

Improvements to GPS performance are often incremental, achieved by squeezing better performance out of existing systems with clever tweaks, smarter analysis and sharper receivers. Then again, every once in a while, there’s a huge leap in the capabilities of the system itself—an advance so big that it makes you appreciate all over again the elegant wizardry of satellite navigation.

The European Union-funded GNSS.asia H2020 project hosted a major roundtable discussion around the theme of “Europe Meets India” at the recent 2019 Munich Satellite Navigation Summit. The event was aimed at promoting cooperation between the GNSS research and industrial communities in Europe and Asia-Pacific.

Satellite navigation has become a global utility, but one that is vulnerable to interference. The European Space Agency’s new NAVISP research and development program is prioritizing research into countering jamming and spoofing of satnav signals, with partner companies exploring varied approaches.
